Although centerless grinding technology has been around for 100 years since the method was patented by Heim in 1917, a great deal of effort was exerted by early research pioneers to understand its rounding mechanism, and significant papers have been published [4,5,6,7,8,9]. The theory of the rounding mechanism has been well established, the setup guidelines for achieving better roundness have been .
One research route that has been explored for about half a century is the development of additives to the grinding mill feed that substantially improve the efficiency .
Research suggests that some jointcracking sounds may be associated with the creation and/or collapse of tiny gas bubbles within the joints. Synovial joints, such as the cervical facet joints in the neck, have a joint capsule filled with synovial fluid that lubricates and protects the .
